NUT-CRACKEH.

SPECIFICATION forming part of Letters Patent No. '7 88,599, dated May 2, 1905.

Application filed November 18, 1903. Serial No. 181,711.

10 all who/1t it may concern.-

lie it known that I, Dn'rLnv LUDWIG Riel-1- ARI) ROGIILITZ, a citizen of the free and Hansea-tic town of Hamburg, in the German Empire, have invented certain new and useful Improvements in Nut-Crackers, of which the following is a specification.

The present invention relates to improvements in nut-crackers, the object being to produce a nut-cracker which is exceedingly simple in construction and sensitive, reliable, and efiicient in use; and with this end in view my invention consists in certain novel features of construction and combinations of parts, as will be be hereinafter fully described with refcrence to the accompanying drawings, wherein Figure 1 is a plan, partly in section, of anutcracker constructed in accordance with and embodying my invention; Fig. 2, a sectional side view on the line I II, Fig. 1; and Fig. 3, a detailed view showing a part of one of the cracker-jaws and the screw-threaded operating-spindle in section.

Similar letters of reference refer to similar parts throughout the figures.

According to my said invention the improved nut-cracker is formed with two crackerjaws a, which are provided with strengthening-ribs c and pivoted at one end to a pivot 6, formed on a curved arm 7/, for retaining the nut in position between the jaws, whereas the free ends of said jaws are connected by a right and left threaded screw-spindle c, worlc ing with their threaded ends in accordinglythreaded openings or holes a of the said jaws, Figs. 1 and 3. I The screw-spindle 0 is, moreover, provided with a handle (Z, by means of which the screw-spindle may be turned in one or the other direction in order to cause the jaws to swing together or to move apart from each other into the opened position shown by Fig. 1. The moving apartor outward-swinging motion of the jaws is limited by suitable stops a, attached to the outermost ends of the spindle coutside thejaws (0. Between thejaws may be interposed an appropriate spring f, adapted to ordinarily keep the jaws in the normal opened position and tend always to return the same to such position in which the jaws are widest apart from each other, Fig. l.

The free end of the arm I), which serves as a support for the nut to be cracked or broken, may be formed in hook-shaped branches 6 which are loosely hooked over the spindle 0, so as not to interfere with the turning of the latter.

By grasping the jaws in one hand and the handle in the other and by turning the handle or spindle'c respectively against the pressure of the spring f the jaws will be caused to approach each other and the shell of the nut inserted between said jaws and resting upon the arm 7) will be more or less broken, according to the power exerted on the handle (Z.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A nut-cracker comprising two jaws pivoted together, a screw having oppositelythreaded ends to engage the jaws, a handle secured to the screw between its ends, and a wire cooperating with the jaws to hold a nut between them, substantially as described.

2. A nut-cracker, comprising pivoted jaws, a screwhaving oppositely-threaded ends to engage the jaws and an arm supported at one end by the jaws and loosely connected to the screw at its other end, to hold a nut between the jaws, substantially as described.

3. A nut-cracker having jaws, a pivot for said jaws, a high-pitched screw engaging the jaws and having oppositely-threadcd ends, an arm forming an extension of said pivot having its free end supported by the screw and a handle to rotate the screw, substantially as described.

4. A nut-cracker having diverging jaws, a screw having oppositely-threaded ends passing through the ends of the jaws, a pivot for said jaws extended to form an arm, the free end of said arm loosely supported on the screw, and a handle secured to the screw between the threaded portions thereof, substantially as described.

A nut-cracker havingdiverging pivoted jaws,a screw having oppositely-threaded ends passing through the ends of the jaws, stops to having an extension to form an arm whose free end is loosely supported on the screw, a spring to hold the jaws normally open, and a handle secured to the screw between the threaded portions thereof, substantially as de- 5 I scribed.
